An allusion of Snow White, Weiss Schnee is German for “white” and “snow” respectively. Not much is known about the character as of yet, but she is the wielder of the Myrtenaster, a rapier equipped with glyphs that channel the energy of Dust.
I’m a little sad that the photo is not as clear as it could be. This was the best I could do given my situation as a judge of the cosplay competition. Maybe next time, I will just go as a photographer. Who knows?
